) Class Starter (refraction, reflection, + EM Waves)

1. What can happen when a wave strikes a barrier? Check all that apply.

• It can be absorbed
• it can be reflected.
• it can go through the barrier
• it can be refracted

2. According to the Law of Reflection, if a wave strikes a barrier at a 60° angle, it will reflect off the barrier at

• a 30° angle.
• a 45° angle.
• a 60° angle.
• a 90° angle.
• the "normal" angle

3. You can see your face when you look in a mirror because

• the surface scatters reflected light.
• the surface absorbs light waves that strike it.
• the surface reflects light waves evenly.
• the surface transmits light waves through it.

5. What is refraction?

• the bending of a wave as it moves from one medium to another
• the bouncing of a wave as it moves from one medium to another
• the bending of a wave as it strikes an opaque surface

6. What causes refraction as a wave move from one medium to another?

• The wave's amplitude changes.
• The wave's wavelength changes.
• The wave's frequency changes.
• The wave's speed changes.
